Hello. The plugin looks like it will do what I want it to (I had a great theme that came with its own shortcode, but had to downgrade to a more rudimentary theme because I work in an industry with an unfortunate number of IE users, and thus must rely on plugins now to get functionality.)

I have no idea how to use this, though. I see that it does all kinds of things, but there's no instructions for how to use all those things it does to spit out a shortcode to put on my page.
